WebIterative Constrained Weighted Least Squares Source Localization Using TDOA and FDOA Measurements Abstract: This paper investigates the constrained weighted least squares (CWLS) source localization problem by using time difference of arrival and frequency difference of arrival measurements. WebAbstract: The two-stage weighted least squares (TSWLS) and constrained weighted least squares (CWLS) are used to locate mobile station with TDOA/AOA hybrid model, and they both have the same measurement matrix that become ill-conditioned when base-station present circular array distribution and Mobile-Station is close to the array center. An …

WebJan 1, 2015 · [ 7] developed an efficient constrained weighted least squares (CWLS) algorithm method, in which the well-known Newton's iterative method is used and the least squares solution is chosen as the starting value to avoid premature convergence to … WebThere are two primary methods used to calculate the TDOA measurement from the signal of an object. In the first method, each receiver measures the absolute time instant of signal arrival (time-of-arrival or TOA) as defined by t i above. A difference in time-of-arrivals between two receivers is then calculated to obtain the TDOA measurement.
